Effects of Transcranial Direct Current Stimulation on the Static Balance Ability of Patients with Back Pain

Journal of Korean Physical Therapy.2019;31(5):328-332. doi:10.18857/jkpt.2019.31.5.328

PURPOSE: This study examined the effects of transcranial direct current stimulation (tDCS) on the static balance ability of patients with back pain.METHODS: The subjects comprised of 30 males and females in their 20s, who were divided into two groups with and without tDCS. The balance posture ratio score was calculated to determine the changes in balance ability before and after the application of tDCS using balance equipment. A paired t-test was conducted to determine the changes over time, and an independent t-test was performed to determine the changes between the groups. The significance level was set to α=0.05.RESULTS: A significant difference in the changes in the static balance ability of CTDCSG between before and after applying tDCS was observed while the subjects' eyes were open (p<0.05). A comparison between the groups after the experiments revealed significantly increased changes in CTDCSG compared to STDCSE (p<0.05). The changes in static balance ability were not significant when the subjects' eyes were closed (p>0.05).CONCLUSION: The application of tDCS positively changed the static balance ability of patients with back pain. The results of this study showed that tDCS could be used as an intervention to increase the static balance ability of patients with back pain in the clinical field. The study results could be used further as foundational data for future studies on tDCS.

Journal of Korean Physical Therapy.2019;31(5):322-327. doi:10.18857/jkpt.2019.31.5.322

PURPOSE: This study examined the influence of the maximal aerobic capacity on the two-year cardiac-related re-hospitalization in patients with heart failure with a reduced ejection fraction (HFrEF) in Korean society.METHODS: The maximal aerobic capacity of the study population (n=95, male 63%) was evaluated using a cardiopulmonary exercise (CPX) testing system. Each patient was followed up for two years to divide the HFrEF patients into two groups according to cardiac-related re-hospitalization: re-hospitalization (RH) group (n=29, 30%) and no re-hospitalization (NRH) group (n=66, 70%).RESULTS: The relative peak VO₂ (mL/kg/min, p<0.001), exercise duration (p<0.001), respiratory exchange ratio (VCO₂/VO₂, p=0.001), systolic blood pressure (SBP) reserve (p=0.004), heart rate (HR) reserve (p=0.007), SBP max (p=0.02), and HR max (p=0.039) were significantly lower in the RH group than the NRH group during the CPX test. On the other hand, the ventilatory efficiency (VE/VCO₂ slope, p=0.02) and age (p=0.022) were significantly higher in the RH group than in the NRH group. In binary logistic regression analysis, the relative peak VO₂ (p=0.001, Wald Chi-square 10.137) was the strongest predictive factor on cardiac-related re-hospitalization, which was followed by VCO₂/VO₂ (p=0.019, Wald Chi-square 5.54). On the other hand, age (p=0.063, Wald Chi-square 3.445) did not have a significant influence on cardiac related re-hospitalization.CONCLUSION: The maximal aerobic capacity, especially the relative peak VO₂, is the strongest factor on cardiac-related re-hospitalization within two years in patients with HFrEF in Korean society.

Journal of Korean Physical Therapy.2019;31(5):311-316. doi:10.18857/jkpt.2019.31.5.311

PURPOSE: Generally, patients with stroke present with decreased balance and increased spasticity following weakness of the paralyzed muscles. Muscle weakness caused by stroke has two causes. This is caused by a decrease in motor output and an adaptive muscle change, resulting in muscle weakness and muscle paralysis. The purpose of this study was to investigate the effect of strengthening exercise on balance and spasticity in chronic stroke patients and to suggest the basis of clinical treatment.METHODS: Twenty subjects were divided into two groups: a lower-extremity strengthening group (experimental group) and a general physical therapy group (control group). The sliding stander equipment was used for the experimental group and a regimen of warm-up exercise, the main exercise routine, and cool-down exercise were used for the muscle strengthening exercise program. Balance and spasticity were measured before and after the training period. Balance ability was measured by the Berg balance scale, the Timed up and Go test and the weight distribution of the paralyzed muscles by the Spacebalance 3D. Spasticity was measured by the Biodex system.RESULTS: After the training periods, the experimental group showed a significant improvement in BBS, weight distribution of the paralyzed muscles, and decreased spasticity when compared to the control group (p<0.05).CONCLUSION: This study supported the hypothesis that lower-extremity strengthening exercise improves the balance and decreases the spasticity of stroke patients. If it is combined with conventional neurologic physiotherapy, it would be effective rehabilitation for stroke patients.

Journal of Korean Physical Therapy.2019;31(5):304-310. doi:10.18857/jkpt.2019.31.5.304

PURPOSE: This study examined the work-related musculoskeletal pain and quality of life of hospital workers.METHODS: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test.RESULTS: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00).CONCLUSION: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

Journal of Korean Physical Therapy.2019;31(5):298-303. doi:10.18857/jkpt.2019.31.5.298

PURPOSE: This study examined the effects of slashpipe exercise on reducing the thickness of the left and right external oblique, internal oblique, transverse abdominis, erector spinae, and multifidus muscles.METHODS: A total of 29 healthy adult men and women were included in the study. They performed trunk flexion in the supine position and trunk extension in the prone position with a slashpipe and weight bar. The external oblique, internal oblique, and transverse abdominis muscles were measured in the supine position, while the erector spinae and multifidus muscles were measured in the prone position. The data were analyzed using the SPSS ver 21.0 statistical program. The difference in thickness between the right and left sides of the trunk muscle was analyzed by repeated measures analysis. The statistical significance level was set to p<0.05.RESULTS: The results showed that the slashpipe exercise reduced significantly the difference in thickness of the oblique internus and erector spinae muscles compared to the weight bar exercise.CONCLUSION: The chaotic fluidity of the fluid filled inside the slashpipe could be used as sensory feedback information on body mal-alignment, which would have positively affected the symmetrical contraction of the trunk muscles as a trigger for self-correction. Therefore, it will have a useful effect not only on the health of the general public, but also on low back patients and athletes with muscle asymmetry.

Journal of Korean Physical Therapy.2019;31(5):292-297. doi:10.18857/jkpt.2019.31.5.292

PURPOSE: This study examined the effects of backward walking training with task orientation on the functional walking ability of children with cerebral palsy.METHODS: This study was a single-blinded, randomized controlled trial with a crossover design conducted at a single rehabilitation facility with cross-over to the other intervention arm following a two-week break. For a total of 12 children with spastic hemiplegia cerebral palsy, the forward walking training group (n=6) underwent training three times a week for three weeks, 40 minutes a day, and the backward walking training group (n=6) was also trained under the same conditions. To identify the functional walking ability, variables, such as the walking speed, stride length, and step length, were measured using a walk analyzer (OptoGait, Microgate S.r.l, Italy).RESULTS: Both groups showed significant increases in walking speed, stride length, and step length (p<0.01). The backward walking group showed more significant improvement in the walking speed from pre- to post-test (p<0.05). The gait characteristics were similar in the two groups (stride length and step length) but the walking speed in the backward walking group showed a mean difference between the positive effects higher than the forward walking group.CONCLUSION: Task-oriented backward walking training, which was conducted on the ground, may be a more effective treatment approach for improving the walking functions of spastic hemiplegia children than forward walk training.

Ki Song KIM ; In Cheol JEON

Journal of Korean Physical Therapy.2019;31(5):286-291. doi:10.18857/jkpt.2019.31.5.286

PURPOSE: This study examined the effects of self-volar gliding combined with a strap and wrist distraction on pain and the active and passive wrist extension range of motion (ROM) in subjects with dorsal wrist pain during partial weight bearing of the hand.METHODS: Thirty subjects (14 males and 16 females) with dorsal wrist pain during partial weight bearing through the hand participated in this study. The two different self-volar gliding techniques were performed for each group. Self-volar gliding using a strap (SVGS) and SVGS and wrist distraction (SVGSD) were performed five times for one week for each group. The active and passive ROM of wrist extension and the peak pressure pushed by the hand at pain (PPHP) were measured. An independent t-test was used to compare the improvements of these elements between the two different self-volar gliding techniques. The level of statistical significance was at α=0.05.RESULTS: The active and passive ROM of wrist extension and PPHP were greater in both self-volar gliding groups after the one week intervention. On the other hand, these parameters were greater in the SVGSD group than in the SVGS group (p<0.05)CONCLUSION: SVGSD is recommended to improve the active and passive ROM of wrist extension and PPHP in subjects with dorsal wrist pain during partial weight bearing of the hand.

Journal of Korean Physical Therapy.2019;31(5):279-285. doi:10.18857/jkpt.2019.31.5.279

PURPOSE: This study examined the effects of spinal stabilization exercises using visual feedback on the gross motor function and balance of the sitting posture in children with cerebral palsy.METHODS: The subjects were 18 children with cerebral palsy aged 8–15 years in the I–III stages of the Gross Motor Function Classification System. The subjects were divided into an experimental group (n=9) and control group (n=9). The experimental group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises using visual feedback. The control group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises without visual feedback. Both groups participated in the experiment twice a week for eight weeks. The Gross Motor Function Measurement was performed to evaluate the changes between pre- and the post-intervention in gross motor function. The Seated Limit of Stability Surface Area was measured to evaluate the changes in trunk balance.RESULTS: Both experimental and control groups showed a significant increase in the gross motor function and trunk balance (p<0.05). The experimental group showed a significant increase in gross motor function compared to the control group (p<0.05). The experimental group showed a significant increase in the dynamic trunk balance in all directions when measuring the Seated Limit of Stability Surface Area (p<0.05).CONCLUSION: Spinal stabilization exercises using visual feedback for the neurodevelopmental treatment of children with cerebral palsy can improve their gross motor function and trunk balance when in a sitting posture more effectively.

Journal of Korean Physical Therapy.2019;31(5):273-278. doi:10.18857/jkpt.2019.31.5.273

PURPOSE: The purpose of this study was to investigate the effects of three-dimensional virtual reality horse riding simulator training using a head-mounted display on gait and balance in children with cerebral palsy.METHODS: Ten children with cerebral palsy were randomly assigned to the horse riding simulator (HRS) group (n=5) or the horse riding simulator with virtual reality (HRSVR) group (n=5). To evaluate balance, center of gravity (COG) sway velocity and total sway distance of each group were assessed using the Wii balance board, and gait speed and stride length of each group were assessed using a gait analysis system.RESULTS: Intra-group comparisons between pre- and post-intervention measures revealed that there were significant changes in all gait and balance variables such as stride length, gait velocity, COG sway velocity and COG sway distance in the HRSVR group (p<0.05). In the HRS group, there were significant changes in all variables except stride length (p<0.05). In addition, inter-group comparisons showed significant differences between the two groups in stride length, gait velocity and COG sway distance except COG sway velocity (p<0.05).CONCLUSION: The findings of this study suggest that horse riding simulator training combined with 3D virtual reality can be a new positive therapeutic approach for improving functional performance in children with cerebral palsy.
